Eminem surfaced for a rare hour-long performance Wednesday at a party for G-Shock's 30th Anniversary in New York City. The "Shock the World" party featured various star-studded guests, and even though the Detroit-born emcee didn't reveal any new material, he still excited the crowd with many older favorites.

Eminem's performance at the "Shock the World" party spanned from his much earlier classic albums like The Slim Shady LP and The Marshall Mathers LP all the way up to his most recent project, Recovery. The concert opened with Yelawolf, who is signed to Shady Records and is a part of rap group Slaughterhouse, followed by Shady himself.

Mathers and his hype man, Mr. Porter of rap group D12, took the stage while he rapped "Kill You," "Stan," "Criminal," "The Way I Am," "Cleanin' Out My Closet," "Sing For The Moment," "Like Toy Soldiers" and "No Love." He also included his verse from B.O.B.'s "Airplanes" and brought up longtime collaborator Royce Da 5'9" for their song "Lighters."

Finally, Em wrapped up the set with his 2010 single "Not Afraid" off of Recovery all while wearing a G-Shock watch-- the rapper will also have his own line of watches with the brand. After various chants for an encore, however, the rapper returned for his hugely popular Academy Award-winning song "Lose Yourself" from the movie "8 Mile."

"We fully expect to be releasing a new Eminem album in 2013. He's been working on it for some time. It's safe to say that it will be post-Memorial Day at some point, but we're not exactly sure when. We've got some dates locked in for him to perform live in Europe in August, so we're trying to see what else lines up," Rosenberg said in a public statement back in February.

Rumored names for the album include NiNE and Redemption, which have been floating around the internet for the past few months. In August the rapper confirmed that he had been working on the album, but had little time due to his commitment to his rap group Slaughterhouse.

"I actually started my album," Eminem told Michigan radio station Channel 95.5. "But I haven't fully went in yet because I've been finishing up this Slaughterhouse record. I've kind of been really hands-on with this album for the past year."
